Mark 6 Nuclear Bomb
The Mark 6 nuclear bomb was an American nuclear bomb based on the earlier Mark 4 nuclear bomb and its predecessor, the Mark 3 Fat Man nuclear bomb design. The Mark 6 was in production from 1951 to 1955 and saw service until 1962. Seven variants and versions were produced, with a total production run of all models of 1100 bombs. The basic Mark 6 design was in diameter and long, the same basic dimensions as the Mark 4. Various models of the Mark 6 were roughly 25% lighter than either the Mark 4 or Fat Man, and weighed . Early models of the Mark 6 used the same 32-point implosion system design concept as the earlier Mark 4 and Mark 3; the Mark 6 Mod 2 and later used a different, 60-point implosion system. Various models and pit options gave nuclear yields of 18, 26, 80, 154, and 160 kilotons for Mark 6 models. Survivors There are several Mark 6 casings on display: * Defense Nuclear Weapons School on Kirtland Air Force Base in Albuquerque, New Mexico * Cold War Gallery of th ...

W13 Nuclear Warhead
The Mark 13 nuclear bomb and its variant, the W-13 nuclear warhead, were experimental nuclear weapons developed by the United States from 1951 to 1954. The Mark 13 design was based on the earlier Mark 6 nuclear bomb design, which was in turn based on the Mark 4 nuclear bomb and the Mark 3 nuclear bomb used at the end of World War II. Description The Mark 13 bomb was nearly the same size as the Mark 6 nuclear bomb it was developed from; 61 inches in diameter and 128 inches long (150 cm by 320 cm), weighing 7,400 lb (3,300 kg). The W-13 warhead was somewhat smaller, being roughly 58 inches in diameter and 100 inches long, with a 6,000 to 6,500 lb weight (145 cm by 250 cm, 2,700 kg to 2,900 kg).Complete list of all US nuclear weapons Carey ...

Cold War Aerial Bombs Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

1958 Mars Bluff B-47 Nuclear Weapon Loss Incident
The 1958 Mars Bluff B-47 nuclear weapon loss incident was the inadvertent release of a nuclear weapon from a United States Air Force B-47 bomber over Mars Bluff, South Carolina. The bomb, which lacked the fissile material, fissile pit (nuclear weapon), nuclear core, fell over the area, causing damage to buildings below. Though there was no nuclear detonation, six people were injured by the explosion of the bomb's conventional explosives. The Air Force was sued by the family of the victims, who received , . Description of incident On March 11, 1958, a U.S. Air Force Boeing B-47E-LM Stratojet from Hunter Air Force Base operated by the 375th Bombardment Squadron of the 308th Bombardment Wing near Savannah, Georgia, took off at approximately 4:34 PM and was scheduled to fly to the United Kingdom and then to North Africa as part of Operation Snow Flurry. The aircraft was carrying nuclear weapons on board in the event of war with the Soviet Union breaking out. Air Force Captain Bruce ...

List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. United States US nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W-91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other r ...

Ivy King
Ivy King was the largest pure- fission nuclear bomb ever tested by the United States. The bomb was tested during the Truman administration as part of Operation Ivy. This series of tests involved the development of very powerful nuclear weapons in response to the nuclear weapons program of the Soviet Union. The production of Ivy King was hurried to be ready in case its sister project, Ivy Mike, failed in its attempt to achieve a thermonuclear reaction. The Ivy King test actually took place two weeks after the Mike test. Unlike the Mike bomb, the Ivy King device could theoretically have been added to United States' nuclear arsenal, because it was designed to be air-deliverable. On November 16, 1952 at 11:30 local time (23:30 GMT) a B-36H bomber dropped the bomb over a point north of Runit Island in the Enewetak atoll, resulting in a 540 kiloton explosion at . The tropopause height at the time of the detonation was about . The top of the King cloud reached about with the mushr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiloton
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a tonne, metric ton (1,000 kilograms) of Trinitrotoluene, TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 tera-, terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 peta-, petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various CTBT, n ...

Enriched Uranium
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, naval propulsion, and smaller quantities for research reactors ...

Mark 18 Nuclear Bomb
The Mark 18 nuclear bomb, also known as the SOB or Super Oralloy Bomb, was an American nuclear bomb design which was the highest yield fission bomb produced by the US. The Mark 18 had a design yield of 500 kilotons. Noted nuclear weapon designer Ted Taylor was the lead designer for the Mark 18. The Mark 18 was tested once, in the Ivy King nuclear test at the Enewetak atoll in the Pacific Ocean. The test was a complete success at full yield. Description The Mark 18 bomb design used an advanced 92-point implosion system, derived from the Mark 13 nuclear bomb and its ancestors the Mark 6 nuclear bomb, Mark 4 nuclear bomb, and Fat Man Mark 3 nuclear bomb of World War II. Its normal mixed uranium/plutonium fissile core ("pit") was replaced with over 60 kg of pure highly enriched uranium or HEU. With a natural uranium tamper layer, the bomb had over four critical masses of fissile material in the core, and was unsafe: the accidental detonation of even one of the detonato ...

Nuclear Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...
